HELP PLEASE! I have fitted loads of 55021’s and in all cases the lights appeared to work ok except in cases where the Speed Steps were out that can give strange results like flickering lights. On this Loco on Analogue all the Lights were working just fine with 3 at front and 1 at rear correctly showing in each direction. So the Chip has been fitted and nothing. CV Values changed as appropriate as follows:- 29 = 5 (Chip says 28 speed steps not supported on LGB Programming to reverce direction) 49 = 32 Default 50 = 32 Default 51 = 0 us Button 9 52 = 128 Default 53 = 64 Default Changed to Massoth Hand Held and tried 14/28 and 128 Speed Steps all had no effect on lighting but the Loco still ran ok. Anything obvious that I have missed please?

Nah mine had a Direct Decoder Sticker and the 4 Spigots to put the wires to. No Decoder circuit removed, it was a Blue one like 70246 which is indeed a Direct Decoder Loco. But the sticker on the bottom is certainly 23460? Hmm curious.

Decoder wired in as above to 4 spigots on the board. Bulbs were the flat topped ones that I thought were the DCC higher voltage ok ones. Nothing changes by using the Cab Switch, have used Track Power on lower voltage lights before and they do not pop immediately so curious and confusing.

Probably best if I pop the Top off again to take a couple more pictures of the beast and underside.

A typo of mine cv51 0 to USE BUTTON 9? Thanks John. Will try the other options.

Meanwhile here are a couple of pics of the beast, as can be seen inside it was certainly a All Blue one as per 70246 Direct Decoder as shown on the base. Which makes things a little odd as according to the LOK Book 23460 is a Chip Board Fitted FO one. As this was a second hand one from a well known emporium one wonders if a little mix and match had been going on? I am beginning to wonder if that board really is a Direct Decoder one as it does not have a set of Plug Holes for the Decoder? If so I have botched it into an old banger but at least it runs OK.

Aa you say weirder and weirder, just thinking through out loud what to do next, would try the decoder connected to a test rig chassis, just to confirm it's still working.

Then I'd jerry rig a couple of cables up to try the "pins" for the lights on the decoder, multimeter first, test for voltage, then either bulb or LED with a resistor, will either confirm yes or no that the decoder light outputs operate as they should, if yes, closer inspection of the 23460's innards, would be next.

Oh so with the 6 wires from the Plug connected to the appropriate 6 pins on the Decoder as in the diagram from John S, I also need to connect the 4 wires from the Decoder to the Loco as I originally did! Hm thanks will try that today. Many thanks Muns.

Can you help with another matter? I am after a spare 6 pin Plug to go on my Massoth Central Station. The Green one where the wires screw into the Terminals and the Plug goes in the back of my CS. I have the original in my Shed and would like another in my workshop. Thus enabling me to connect up the Massoth Central Station to my Test Track indoors whe the need arises.

So thanks to Muns and now PhilP all is well. They say you do not know what you do not know and I did not know about this form of Direct Decoder. In the past I have always just plugged them in! Pic below shows all the wires in case anyone else runs into the same issues that I did not knowing what they did not know etc. And note all the Dip Switches are not set at On.

Still all is well and Lights all now working ready to be delivered to Somerset next time I visit. Labelling is MkB for Mikeysbahn Bahn. Number 16 as per the Chip. Pic below on the Test Track to show what she looks like after I have completed the repaint from Blue. Should go nicely with Mike’s other RHB Brown Electric Locomotives.

As ever although I got the beast running, I wanted it forwards with the Driver at the Front and CV adjustment would not achieve that, also the lighting was correct for forwards going backwards to me. My DCC Brain tried a few options with no change then the Analogue part of the brain kicked in. Swopped the 2 Motor Wires around Yellow and Green on the Pins of the above pic of the insides. Success.
